Date: Wed, 28 Feb 2018 14:15:58 -0800	[thread overview]
Message-ID: <20180228221609.11265-1-jcmvbkbc@gmail.com> (raw)

Hello,

this series adds linux-user support for target/xtensa.
It starts with a small cleanup for xtensa registers dumping.
It adds support for debugging linux-user process with xtensa-linux-gdb
(as opposed to xtensa-elf-gdb), which can only access unprivileged
registers.
It then enables MTTCG for xtensa.
It continues with a cleanup in linux-user/mmap area making sure that it
works correctly with limited 30-bit-wide user address space.
It then imports xtensa-specific definitions from the linux kernel,
conditionalizes user-only/softmmu-only code and adds handlers for signals
exceptions, process/thread creation and core registers dumping.

Changes v1->v2:
- add definition of TARGET_TIOCGPTPEER to linux-user/xtensa/termbits.h
- Cc linux-user maintainers
